![]() Concorde flew with a cruise speed of about 2,100 km per hour, twice the speed of sound.Concorde was jointly developed and produced by British and French engineers. ![]() But the desire to reach any major destination on earth in just a fraction of the current travel time, still triggers scientists and engineers from all over the world. There are enormous technical challenges to overcome, and it will take several decades before we will see supersonic or hypersonic aircraft in commercial aviation. One step is to develop a commercial supersonic business jet flying at mach 1.5. Airbus recently patented a design that will fly 4.5 times the speed of sound, enabling flying Amsterdam-New York in just an hour! Several design studies to next generation high speed commercial aircraft are ongoing. We are a partner in the XCOR Space project: a project developing commercial space flight one of the operation sites will be Curacao. In this concept a 40 minute flight into space will be made possible taking off and landing in a space plane from a conventional runway. KLM is participating in the development of this type of air transport. These type of aircraft will take off like a current type aircraft from a runway at an airport but will climb through outer space and then at the destination will re-entry the atmosphere again and land like a conventional aircraft. The goal is to achieve higher speeds with more efficient operation. Outer spaceĪ next development might be the evolution into a combination of atmospheric and non-atmospheric flights by this the flight follows a trajectory partly in the atmosphere and partly in outer space. Remember, Concorde flew at a speed of 2,100 km per hour, with newer generations high speed air travel will more then double that speed, enabling Amsterdam New York in just less then two hours!Ī possible roadmap to commercial hypersonic flights is first to develop commercially viable supersonic type of aircraft that operate in earth’s atmosphere as we are doing right now with commercial aviation. Image credit: Ger Buskermolen New developmentsĪlthough there were just a limited number of supersonic commercial aircraft sold, there is still a lot of research going on to travel with speeds that will enable reaching far away destinations at the globe within just a few hours. ![]() The Concorde was the most famous one a joint design by France and Great Britain. NASA Dryden’s F-15B Research Tes. Image credit: NASA / Tom Tschida The famous ConcordeĬommercial aircraft able to fly faster than the speed of sound were developed in the nineteen sixties. A famous rocket type aircraft that still holds the world record is the X-15, which achieved a speed of Mach 6.72 or 7,274 kilometers per hour. A lot of research was done with the development and research to manned space flight. History of supersonic flightĭevelopment of supersonic flight started already in the early fifties of the 20 th century, initially mainly driven by military developments. We call this subsonic flight. Concorde flew with a cruise speed of about 2,100 km per hour. The future generations of very fast commercial aircraft will fly with speeds of 4-5 times the speed of sound, that is in the range of 4,000-5,000 km per hour. Image credit: NASA Subsonic flightĬurrent commercial aircraft fly with a cruise speed depending on the model and make of the aircraft that ranges between Mach 0.81 through Mach 0.86, that is a speed in the range of 900 km per hour. Its technologies – the F-100-like propulsionsystem, a tail blister, and the overall shape – are combined to achieve a lower target perceived decibel level. This concept of an aircraft that could fly at supersonic speeds over land is being used by researchers, especially at NASA’s Langley Research Center, to continue to test ideas on ways to reduce the level of sonic booms. Hypersonic flight is defined as flights that take place at Mach 5 and above 5 and more times the speed of sound! At 20 degrees Celsius and at sea level the speed of sound is 343,2 meters per second which is 1,236 kilometers per hour. ![]() That’s why we use a certain temperature and altitude to define the speed of sound. The temperature of the atmosphere and the altitude affects the speed of sound. Supersonic flight is a flight that takes place with a speed faster than the speed of sound. What is the difference between supersonic flight and hypersonic flight? In this blog I’d like to tell you about another interesting area of research and what might be the future of traveling by plane: supersonic and hypersonic flight. In my previous blog I wrote about an airplane design with a blended wing body with engines that can operate on different fuel types. Save Saved Save for later Saved for later
